2.5.4. Check of system of injection
Check of the operating pressure
The operating pressure is checked on the car by means of a tee of KDEP 1034 established on the delivery pipeline connecting the batcher distributor to the regulator of the operating pressure. The manometer with a scale to 6 kg/cm 2 is connected to the third union of a tee.

Installation of a tee for measurement of the operating pressure |
After an inhaling of all unions several times open and close cranes, having lowered the manometer on a connecting hose as low as possible to remove air from system. After that suspend the manometer to a cross-piece of a cowl or in any other place where its indications will be easily read out.
